Sample comprised of nurses (N=200) with the age range 20-30 years (M= 25.6, SD=3.4). EQ-i 125 (Bar-On, 1997) and Psychological Adjustment Scale (Sabir, 1999) were administered on designated sample to measure emotional intelligence and psychological adjustment respectively. A demographic form was used to collect data on other variables i.e., wards, hospitals, professional experience. Findings indicated the positive correlation between emotional intelligence and psychological adjustment of nurses. Simple regression analysis indicated that psychological adjustment, hospitals (private/government) and professional experience emerged as significant predictor of EQ while wards (emergency/non-emergency) were neither correlated with other variables of interest nor significantly predicted EQ. In addition...

Research paper thumbnail of Systematic review and meta-analysis of prevalence of, and risk factors for, pelvic floor disorders in community-dwelling women in low and middle-income countries: a protocol study

BMJ open, Jan 8, 2017

Pelvic floor disorders (PFDs) including urinary incontinence, faecal incontinence and pelvic orga... more Pelvic floor disorders (PFDs) including urinary incontinence, faecal incontinence and pelvic organ prolapse are common debilitating conditions among women in high-income countries. However, PFDs in women in low/middle-income countries (LMICs) have not been studied extensively. We aim to conduct a systematic review and meta-analysis of the available literature to determine the prevalence of, and/or risk factors for, PFDs in women in LMIC. We will search electronic databases including MEDLINE, EMBASE, PsycINFO, CINAHL, Maternity & Infant Care and Google Scholar for eligible studies. Inclusion criteria will be observational studies of healthy women, which have collected data using validated or non-validated tools, are published in English and were conducted in community women in LMICs, defined by the World Bank. A standardised data extraction form will be developed and piloted, based on the template of the Cochrane good practice data extraction form. All included studies will be assess...

Research paper thumbnail of DPPH Scavenging Assay of Eighty Four Bangladeshi Medicinal Plants

Stock solution of different plant extracts and standard were diluted to achieve suitable concentrations. A control was also prepared without plant extract solution. Then 0.004% DPPH solution was added. The mixtures were incubated in the room temperature for 30 minutes. Then the absorbance was measured at 517 nm against solvent in UV-spectrophotometer and then IC50 was calculated. In this experiment two standard were usedascorbic acid and BHT. Both showed a significant IC50 value of 15.5µg/mL, and 46.54µg/mL respectively. Among 84 medicinal plants Syzygim cumini, Casuarina littorea, Borassus flabellifer, Enhydra fluctuans, and Minusops elengi exhibited highest radical scavenging potential with an IC50 value of 12.816µg/mL, 14.467µg/mL, 15.755µg/mL, 15.653µg/mL, and 20.380µg/mL respectively. All these value are very close to the IC50 value of ascorbic acid and better than IC50 value of BHT (Butylated Hydroxy Toluene). Syzygim cumini is the most powerful scavenger among all tested medicinal plants and also most strong scavenger than ascorbic acid and BHT. Scavenging activity was found to increase in dose dependent manner. Another 30 medicinal plants exhibited good scavenging property and 14 medicinal plants showed moderate scavenging activity. The rest presented lower scavenging activity. This present study indicates that plants having good scavenging property may have various health beneficial effects and these plants can be considered as valuable source of bioactive components with high antioxidant properties.

Research paper thumbnail of Tractor beam for fully immersed multiple objects: Long distance pulling, trapping, and rotation with a single optical set-up

Research paper thumbnail of Material Independent Long Distance Pulling, Trapping, and Rotation of Fully Immersed Multiple Objects with a Single Optical Set-up

A necessary theoretical solution of these problems is proposed here. This article demonstrates a novel active tractor beam for multiple fully immersed objects with its additional abilities of yielding a controlled rotation and a desired 3D trapping. Continuous and stable long distance levitation, controlled rotation and 3D trapping are demonstrated with a single optical set-up by using two coaxial, or even non-coaxial, superimposed non-diffracting higher order Bessel beams of reverse helical nature and different frequencies. The superimposed beam has periodic intensity variations both along and around the beam-axis because of the difference in longitudinal wave-vectors and beam orders, respectively. The difference in frequencies of two laser beams makes the intensity pattern ...
